Application August 25, 1950, Serial No. 181,407

4 Claims. 1

This invention relates to a grill for cooking food over a fire and more particularly to an'adjustable grill for cooking over an open fire and positioning the food at different distances from the fire.

It is among the objects of the invention to provide a grill assembly for cooking food, such as meat or fish, over an open fire, which assembly includes a supporting post, a grill having an opening slidably receiving the post and means supporting the grill from the post at selective positions of adjustment along the post and permitting rotation of the grill about the post so that the grill can be moved up and down relative to a cooking fire and either end of the grill can be swung toward or away from the fire, which is easy to set up in operative condition and can be disassembled and reduced to a highly compact condition for transportation and storage, and which is simple and durable in construction, economical to manufacture, and easy to use.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawings wherein:

Figure 1 is a top plan view of an adjustable grill assembly illustrative of the invention;-

Figure 2 is an end elevational view of the grill assembly illustrated in Figure 1;

Figure 3 is a side elevational View of the grill assembly; and

Figure 4 is a cross sectional view on the line 44 of Figure 1.

With continued reference to the drawings, the grill assembly comprises an elongated post it! which may conveniently be formed from a suitable length of metal tubing having a conical extension I I secured to one end thereof to provide a suitable point for forcing the post into the ground.

The grill i2 is of elongated, rectangular shape and includes a wire frame It of rectangular shape, a plurality of longitudinally extending bars I4 disposed at substantially uniform intervals between the side portions of the frame I3 substantially parallel to the frame side portions and to each other and a plurality of transverse bars I5 extending between the frame side members and disposed at substantially uniform intervals therealong, the transverse members being substantially parallel to each other and substantially perpendicular to the-longitudinal bars I4. The longitudinal bars I4 are preferably interwoven with the transverse bars IE to provide a grid structure within the grill frame upon which articles of food to be cooked can be conveniently supported.

An annular collar I6 is secured in an opening in the grid substantially at the center of the grill and slidably receives the post Ill, permitting the grid to move up and down longitudinally of the post and to rotate about the post.

A bracket sleeve I! slidably receives the post I!) above the grill I2 and a plate I8 of elongated, rectangular shape is secured intermediate its length to the lower end of the sleeve I1 and is provided with apertures disposed one near each end of the plate and one in alignment with the bore of the sleeve I] to slidably receive the post.

A second plate is is spaced below the plate I8 and provided with apertures which are respectively in alignment with the apertures in the plate I8. A bolt 2!) extends through the apertures in corresponding ends of the two plates i8 and I9 and has at one end a head 2i resting upon the upper surface of the plate I8 and at its other end a nut 22 bearing against the under surface of the lower plate It. A spacer sleeve 23 surrounds the bolt between the plates [8 and ill to maintain the corresponding ends of these plates spaced apart at a predetermined distance.

A bolt Ell extends through the apertures at the opposite ends of the plates I8 and I9 and this bolt has a head 25 bearing against the under surface of the lower plate I9. The bolt 24 is longer than the bolt 2!] and extends through the side of the plate I8 remote from the plate Hi. This bolt carries a nut 26 on its end remote from the head 25 and a spring abutment washer 2i bears against the under side of the nut. A coiled compression spring 28 surrounds the bolt 24 between the upper side of the plate I8 and the washer 2i and tends to lift the corresponding end of the lower plate I9, thereby cramping the plate is relative to the post It to hold the sleeve 1'! at selective positions of adjustment along the post. The plate I 9 extends outwardly beyond the corresponding end of the plate I8 receiving the bolt 2i to provide a lever for manually moving the plate is against the force of spring 28 to relieve the cramping action of the plate I9 relative to the post and free this assembly for sliding movement up or down the post. When the plate I9 is released, the spring 28 will cause it to cramp relative to the post, as explained above, to hold the sleeve IT at the selected position of adjustment.

An elongated bar 30 has at its mid-length location an annular enlargement 3! in which the end of sleeve l! remote from plate I8 is secured. The portions of the bar 30 at the respectively opposite sides of the enlargement 35 extend perpendicularly outwardly from the sleeve H and post E0 in respectively opposite directions and to substantially the same extent.

A pair of bails 32 and 33 are suspended one from each end of the bar 39 and are connected at their ends to the end portions of the rectangular grill frame I2 near the corresponding corners of the grill. The bar 36 is of elongated, rectangular cross sectional shape and the balls 32 and 33 have at their mid-length location U- shaped formations 34 and 35 respectively of gen erally rectangular shape closely receivin the corresponding portions of the bar 30 to support the bails on the bar against rocking movement of the former relative to the latter. At their ends the bails are provided with eye formations, as indicated at 36, surrounding the corresponding end portions of the grill frame to firmly secure the bails to the grill. The bails thus extend longitudinally of the grill at the opposite sides thereof and in planes substantially parallel to the adjacent side portions of the grill frame.

With this arrangement, the grill 2 is firmly held against rocking movements relative to the post but can be rotated freely around the post so that either end of the elongated grill may be placed over the fire or swung away from the fire, as may be desired, and the grill may be adjustably moved up and down the post to move it closer to or further away from the fire and is releasably supported on the post at any desired position of adjustment therealong.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof, The present embodiment therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoin description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.

What is claimed is:
